feedback only comes when mic is connected, are you using mic? like karaoke ?

anyway the noise you hear might be coming from the preamp s section, most probably if there are crossover built-in in your amp, try to change settings and lower it down, might help

usually because of bad ground try using a wire brush to remove any corrosion, paint, and or rust under ground wire
